    摘要: A touch structure (01), a touch panel and a display device are provided. The touch structure (01) includes a plurality of repeating units (02), each repeating unit including a first touch electrode (10) and a second touch electrode (20) intersecting with and insulated from each other, the first touch electrodes (10) being connected in a bridging manner. A dummy electrode (40) is further provided in a region of each repeating unit not provided with the first touch electrode (10) and the second touch electrode (20). A first trench (301) and a second trench (302) are provided respectively between the dummy electrode (40) and the first touch electrode (10) and between the dummy electrode (40) and the second touch electrode (20); and a third trench (303) is provided between the dummy electrodes (40) located in adjacent repeating units. The dummy electrode (40) includes at least 2 sub-dummy electrodes (401), and a fourth trench (304) is formed between adjacent sub-dummy electrodes (401) located in any one of the dummy electrodes (40). Edges of the first trench (301), the second trench (302), the third trench (303) and the fourth trench (304) all have a plurality of bending points.
